Please pay particular attention to the detergent dosage indicated by the manufacturer for the type of detergent and the hardness of the local water. If you use insufficient detergent, amongst other things, lime could be deposited on the linen, making textiles hard to the touch and causing white textiles to become dull and coloured textiles to fade. Moreover, lime deposits on linen cause premature wear and tear and stains are more difficult to wash out. You should therefore reduce the amount of detergent if you only have a small load.
